I was skeptical at first but I’ve been using it for about 2-3 months, and it runs every day at 6am and it has never failed me. It always has a full filter at the end for the week, and the app is very good. When it would get stuck in places, it would always find a way out and I’ve never had to manually fix it. What’s even better is that there are 100-300 dollar roombas out there and yet this one has outperformed the expensive ones. They even are going to send me 4 free filters and 4 free brushes just for using it daily.

Doesn't last

Color: White

This product was working well. I used it daily but all of a sudden after 8 months it just stopped charging. I wish it actually lasted because it was a great product. But since it now no longer charges its of no use and a waste of money smh

Good quality and good value

Size: 2+6+1+12 Pack

this is a great deal and so nice to have on hand. I like being able to just grab replacement parts as needed and not have to place orders for them. It gives peace of mind to know I already have them on hand. much more affordable to buy all at once too
